CARBURETER.

SPECIFICATION forming part of Letters Patent No. 690,303, dated December 31, 1901.

To all whom it may concern.'

Be itknown that I, JAMES ST. CLAIR LEGGE, en gineer, a citizen of England, residing at No. 16 St. Hele'ns Place, in the city of London,

England, have invented certain new and useful Improvements in Apparatus for 4Garbu reting Air, (for which I have made application for a patent in GreatBritain, No. 9,513, dated May 7, 1901, and in France, dated May 9,1901,

ro No. 299,242,) of which the followingis a specication.

This invention relates to apparatus for carhureting air-that is to say, mixing with it vapor of a volatile hydrocarbon liquid, so as to produce an inflammable mixture available for heating orlighting purposes.

The accompanying drawing is a longitudinal section of apparatus according to this invention.

2o a is a drying vessel having an inlet h and an outlet c for air supplied to it at moderate pressure by a fan, blower, or other suitable means. In this vessel, which` has a removable cover d, are holders e, having perforated bottoms and containing quicklime or calcium chlorid, through which the air passes, becoming dried. n

f is the carbureting vessel, containing in its lower part the hydrocarbon liquid g and above 3o a perforated partition h fragments c' of pumice-stone or other porous material. From the outlet c of the drying vessel a a pipe leads having two branches provided .with valves or stop-cocks, the one branch j leading to a coil k of perforated pipe immersed in the liquid, the other, l, leadingto a coil m of perforated pipe under the porous material il. l The vessel fhas its sides and bottom water-jacketed, 'and immersed in the hydrocarbon liquid is a pipe- 40 coil n, both ends of which communicate with the Water of the jacket. From the roof of the vessel f, part of which, o, is removable, is an outlet-pipe p, provided with a valve or stopcock and leading to a suitable gas-holder,

q is a feed-regulating vessel communicating above and below with the vessel f and containing a float r and a valve s, covering the mouth of a pipe t, which is provided with a stop-cock and communicates with a reservoir 5o of hydrocarbon liquid situated at a somewhathigher level.

On the upper part of a pipe t', leading up f rom the valve-case, are pivoted two levers u,

the long arms of which rest ou the float r, and the short arms are connected to a rod w, extending down to the valve s. l When the level ofthe liquid in the vessels f and q is lowered, the float r descends, raising the rod w, and fresh liquid entersby the pipe t, raising the valve s until the level of the liquid is raised, 6o raising the float and the long arms of the levers u, the short arms of which depress the rod w, closing the valve s. Thus the hydrocarbon liquid in fis maintained lat a constant level, and the excessive cooling due to its evaporation is also prevented by Water caused to circulate through lthe jacket and coil n. The dried air from ct passes partly by the branch pipej to the pipe-coil kland issues through its perforatious through the liquid, taking up va- 7o por. The dried air also passes partly by the branch pipe l to the coil m and issues through its perforations. Both portions of the airthat which is carbureted by passing through the liquid and that which is not carburetedpass through the porous material 1l, the air and vapor becoming thoroughly mingled, so as to form a combustible mixture,which passes by the pipe p to the gas-holder. By adjusting the valves or stop-cocks of the branch 8o pipes j and Z more or less of the air can be carbureted, producing a more or less combustible mixture, as may be desired. Also by this adjustment the action ot' the apparatus can be made constant, or nearly so, notwithstanding great variations of external temperature, all or nearly all the air being passedthrough the liquid in cold weatherand a smaller quantity in hot weather, when the liquid evaporates more freely. 9o

Having thus described the nature of this invention and the best means I know for carrying the same into practical effect, I claim- Apparatus for carbureting air comprising an air-drying vessel containing material absorptive of moisture, an inlet for air thereinto, an outlet having two valved branch pipes terminating in coils of perforated pipe, a carbureting vessel in two compartments separated by a perforated partition, the one perroo forated coil situated below the partition and immersed in liquid hydrocarbon the other perforated coil and a deep layer of porous matemy hand in presence of two subscribing Witrial above the partition, a, Water-jacket suruesses. 4 roundinCr and a pipe-Coil immersedin the hydrocarbn, and a vessel for supplying the hy- 'I' ST' C LEGGE 5 drooarbon provided with a float', and valve, Witnesses:

substantially as described. GERALD. L. SMITH,
